No. The closest to that would be me wearing something like a bracelet that I got as a gift as some kind of good luck charm. But I don't actually believe it gives me luck or anything, just helpse feel closer to the person that gave it to me.

Also stuff like routines/rituals before doing something stressful/high stakes/important. Logically I know that it has no impact, but it helps calm the nerves to have a set routine before performing the action.
